I am 34 y/o male. I have had two episodes of Atrial Fibrilaltion in the past 6 years. Drs. put me on Atenolol, Xanax and Zoloft because I was having panic attacks about the AFIB. Last year went off all meds and was feeling great. For the past month or so I have woken up in middle of night with feeling like my heart is racing and lots of adreniline. Not a full blown panic. I put on a blood pressure monitor and my BP is a little elevated and the heart rate is normal. I feel like it is going nuts though. I also feel like I am short of breath but I am not really. I can relax and breath through my nose just fine. I think it may have to do with indegestion and reflux. Does anyone else have experience with this?
